Fuel pump....

....for a Hayabusa. What to go for?

Want to future proof it just in case, so reckon 204L/hour at 3 Bar is enough? Lock out is 11 Bar. Or should I be looking for more?

The standard hayabusa fuel pump is capable of flowing up to 200bhp worth of fuel,any tuning above this level starts showing a lean condition,where an upgraded pump is needed.

Hence the part where I said future proofing! I dont have the standard pump and I dont know what its rated at either which brings me back to the question!

If you want to go over 200 bhp safely you will need a Bosch 957 fuel pump rated for up to 5oo bhp a large bore fuel rail,a set of bigger injectors, std injectors are only 240cc and a suitable pressure regulator, such as aeromotive.

Aeromotive regulator fitted with a SPA digital fuel pressure guage. Uprated fuel rail good for around 600bhp. Injectors are stock, (at the moment). All fuel lines are -6.
